proximal renal tubular acidosis

Proximal renal tubular acidosis is a condition where the kidneys have difficulty reabsorbing bicarbonate, a substance that helps keep your body's pH balanced. Normally, the kidneys filter bicarbonate from the blood and then reabsorb most of it back into the bloodstream. In this condition, this process is impaired, leading to excess acid in the body and a drop in blood pH, causing acidosis. This can result in symptoms like fatigue, bone weakness, and growth issues, especially in children. It may be caused by genetic factors or certain medications, and often requires medical management to correct the acid-base imbalance.
